Original application filed November 12,

Be it known that. we, Josnrrr T. SULLr- VAN and EMILY DELANEYITIURNBULL, citi-.

Zens of the United States, and residents of New Orleans, in the parish of Orleans and Stateof Louisiana, have been appointed eX- ecutors of the estate of WALTER J. TURN- V BULL, deceased, whoduringhis lifetime invented certain new and useful Improvements in Conveyors, of which the following is a specification.

This invention relates to improvements 1n devices for conveying merchandise, as in the operation. of unloading vessels, and it consists in the combinatlons, constructions, and

arrangements herein described and claimed.

The present applicationis a division of a prior application, Serial No. 800,491, filed Now; 12, 1913. v n

An object ofthis invention is to provide a device by means of whichga vessel or other similar carrier may beunloaded in a.m1n1- mumtime and at a minimum cost.

A further object of thejgtinvention is to provide a movable conveyer which may be elevated or loweredto accommodate the heights of difierent vessels,

A furtherobject ofthefinvention is to provide a device of the type described comcordance therewith, thereby providing for a prising an endless conveyer ..which may be run at any suitable speechiand which is ad-,

justable while running softhat as the cargo is lowered the device maybe lowered in acpractically continuous discharge of the cargo.

Other objects and advantages willappear in the following specification and the novel featuresof the device will be pointed out in the appended claims.

The invention is illustrated in the accompanying drawings formingpart of this application in which Figure 1 is a side viewflof the device n its operative lpositionfthefwharf being shown in section, Fig. 2, is a plan view of the device,.Fig. 3 is a bottom View of one of the members which form the endless conveyer, Fig. 4: isa section along the line 4-1l of Fig. 3, Fig.5 isan enlarged side view of a portion of theoperatingmechanism of the conveyer, Fig. 61s an enlarged i plan viewof the upper portion of the conveyer mechanism, and F igii 7} is an enlarged p p p I u gear 16 is designed to be engaged by a bevsectional view on the line 7%? of FigHG.

particularly wharf 18 made. use of, such as that shown the wharf has an inwardly extending cut away portion 4 between opposed posts 3, and the conveyeris designed to "besus portion in the man I pendedin this cut-away ner hereinafter described.

The conveyor proper-consists of a pair of In carrying out the invention any suitable.

Patented ()Jct. 6,1914: Divided andthis application filed March side members suohas those shown at 5 in e r v I I i I v lug. 4. It will be seen from this figure that these side members hear at their upper parts U-shaped angle irons 6, which form runways for the movable parts of the con i veyer. Lower L-shaped angle rons 7 are secured to the side members 5, and form supports for the return portionof'the end-' less conveyer.

The endless conveyor is made UPTOHIE. a j serles of LlIlltS. These are best shownfin Figs. 3 and 4. It will be seen from: these figures that each unit consists i ofaplate8.

having a fiat surface with laterally extend-. ing flanges 8 at the sides- At theends of the plate 8 are lntegral end members 8 having lugs or ears 8, provided with openings 8 The openings in the opposed end mein hers 8" are 1n ahnement, andashaft 9 is passed through the alined openings and bears on its outerends wheels oryrollers 10, p, like those shown inFigs. 5and7. Asfiwill be seen from Fig. 5 the extension or ear 8 of one unit overlaps the. extension of theadjacent unit and the rod 9 is common to both of these units at this point." This provides injreality a series oflong flat and relatively narrow links. On the upper side ofthe con veyer the links form a practically continuous platform, the short space 11 between the links being practically negligible as far as making a continuous surface is concerned.

In Figs. 5 and 6 is shown the. means by which the conveyor is operated. This-com prises; a motor M whoseshaft 12 bears a worm 13. The latter meshes with a worm wheel 14L (see Fig; 6) on a shaft 15. The

latter extends through the side members 5 and bears atone end abeveled gear lGQand atthe other end the sprockets 17 A drum 18is1 also mounted on the shaft 15..jThe* eled 19, which is slidablymounted on a shaft 20. It is held normally out of engagement with the gear 18 by means of a spring 21 (see Fig. 6) but may be brought into engagement with the gear by means of a wedge-shaped yoke 22, which straddles the shaft 20, and which has a handle or shank 23 extending to theopposite side of the machine. l he shaft 20 bears a worm 2%, which engages atom wheel 25 on a shaft 26. The latter bears winding drums 27.

a il be se n m Fi s 1 an 2 a a 28 is'disposed underneath the conveyernear the lower end thereof. This bar is connected with the side'nienibers 5 by means'of inclined braces '29. oabl'es'ao are secured to the bar 28','p,ass upwardly, and around pulleys 31, which are secured to the posts on opposite sides of the conveyer. Counter-weights 32 are carried by the cables 80,. Cables 33 are alsosecured to the cross member 28 and pass upwardly and over pulleys 34 on the front supporting post or. piles 3, thence rearwardly over pulleys on the rear piles or iima n p s hen down ar e pulleys 3'6 onthe side members 5, and thence to thew' hdi s dr '2 on eit si' e'o tlie eonveyer. i

From the foregoing description of the various parts of the device the operation therer of may be readily understood.

"when it is desired to'unioad a vessel such as that shown at 37 1, the operator sets'the starting lever 38 (see Fig. 6) in a peasants start motor M. The revolu ti on'of the latter causes the turning of the I gear 16. Ifnow tlie'haridle 23 is piished forweirdly so to bring the wedge-shaped yoke inhetwe'enthe gear the hanger 39 the ar willhe forced has mesh with the gear 16 will cause the revolution of the shaft "20 i and the winding or unwinding of the cables 33 in accordance with the directionof rotation of the motor, that is to say, the outer "end of the device can be either raisedo r lowered so to accommodate it to the height of the vessel. asse s as the desired height attained the handle 23 is wit drawn and a sp na 21 will force the gear 19" out of mesh with the gear 16 The coiintebalaiicing weights 32 will hold the conveyer at the desired height. The motor n ayiiow be speededu'p to'the required speed for operating the endless conveyer.

It will seen 6 that the sprocketwheels are arranged to receive the rollers 10, so that-when the shaft 15 is revolvii g 'theendl e'ss c onveyer will be operated so as to cause a movement thereof in the direction shQWI i by the "arrows in Fig. 1. Any merehan'disewhich isplaced on thebonv veyer from the deck or unloading platform (see Fig. willbe transported bynreans of the movementof the conveyer onto the dock or warehousefioor, where it maybe received andremoved by anysuitable appa ratus.

One advantage of a device of this kind is that it may be raised or lowered to accommodate the heights of the discharging decks of difierent vessels or in accordance with the ebb and flow of the tide in seaports. The de vice requires no cover and does not in any way obstruct the stage, plank s, derricks, etc., on vessels, as there are no fixtures other than the supporting posts 3 above the wharf level. One operator at the controller has perfect control of the conveyer;
